After a six-year absence, a diesel Beetle is returning for Volkswagen.

The 2013 Beetle TDI is set to be revealed next week at the Chicago auto show, and it will join the naturally aspirated and turbo-powered gasoline variants in the lineup. The 2.0-liter direct-injection diesel is rated at 140 hp and 236 lb-ft of torque, and it’s estimated to get 29 mpg in the city and 39 mpg on the highway. The unit will work with a six-speed manual or dual-clutch DSG six-speed automatic transmission.

Pricing will be announced closer to the summer launch. VW sold diesel Beetles stateside from 1998 to 2006, and they used a 1.9-liter turbo four-cylinder.

The new model offers a sunroof, an audio upgrade and a navigation feature as options.
